Did you know
- The Grundfos CHI series, a horizontal multistage centrifugal pump, was designed for pumping thin, non-explosive liquids and is made of corrosion-resistant materials. The CHIE series is a variant of the CHI, incorporating an MLE motor with a built-in PI-controller for variable speed control.
- The CHI/CHIE series sits within Grundfos's range of horizontal multistage centrifugal pumps, alongside the CM/CME series. The CM/CME series is also a horizontal multistage pump, but it is designed with a focus on compactness, potentially requiring an adapter plate for replacement of older CHI/CHIE models.
- The CHI/CHIE series is chosen for its stainless steel construction in all liquid-contacting parts, making it suitable for industrial applications requiring corrosion resistance. The CHIE model, in particular, offers variable pump performance through its integrated variable frequency drive and system controller, allowing for constant pressure applications and energy savings.
